Using the 28V-Input-Voltage Single-Cell
Li-Ion Charger with 10mA Regulator
(KIT34675EPEVBE)
1
Purpose
Contents
This User Guide helps the Lithium-Ion (Li-Ion)
battery charger designer understand the MC34675
and its evaluation board. It illustrates the design
procedure when using the MC34675 to design a
Li-Ion battery charger, and the way to get the best
performance from the MC34675.

Scope
The MC34675 is a 28V-input-voltage single-cell
Li-Ion battery charger with 10mA regulator in a tiny
2x3 mm TDFN package. It features high accurate
output voltage and charge current. Its high input
voltage of 28V eliminates the over-voltage
protection circuit required in handheld devices. It
uses an external resistor to set the fast charge
current up to 1000mA. The end of charge (EOC)
current is pre-set to 10% of the fast charge current
by factory. When the battery voltage is below the
trickle charge threshold of 2.7V, the MC34675
charges the battery with 20% of the fast charge
current. Two indication pins (PPR, CHG) can be
